A preliminary biopsychosocial analysis of online information on causes of neck pain.

Objective: The aim of the present study was to analyse the freely available online information on the causes of neck pain based on the biopsychosocial model of pain.

Methods: A preliminary biopsychosocial analysis tool was developed, after an extensive literature review of the pathoanatomical and psychosocial contributors for neck pain. The websites that commonly appeared after the search term "causes of neck pain" in the first two pages of the search engines (Google, Yahoo and Bing) were selected for the biopsychosocial analysis.
